Black Holes: Cosmic Vanishing Acts
Black holes occur when a massive star dies. As its outer layers cascade into space, the core collapses to beyond the visible. It becomes a voracious gravitational trap from which nothing, not even light, escapes. Black holes can be detected by bright surrounding disks-material swirling to the event horizon and oblivion. But at the brink, some material hits a shockwave and shoots at right angles from the disk blasting out vast jets and plumes.
